It's not only that, those things went extinct because of things out of their control as a species. Right now we have the means to fix everything, and create some sort of civilization that is somewhat stable. But we don't have the heart or sociopathy or ideology to do things like that. We have a system which is inherently causing problems, but we're happy at least in the idea that it does not make us to do things to each other that would be terrible. So we are incapable as a species of doing things necessary. Now imagine that the civilizations that do practice these sorts of things to survive. I mean evil at levels much greater than Hitler. Imagine how unstable those civilizations are, as power in those types of ideologies is chaotic. So you are in a damned if you do damned if you don't scenario. In either case your ideology and the natural laws of power are working against you. Either people are fighting with each other for their desires to have freedom and rights, or they are fighting for their desires through an economic system at the cost of everything else, environment, etc. So I think what you are hoping for is some blind luck that your systems somehow work themselves out, not because they are good, stable, or functional systems from the perspective of survival but because of blind luck and that somehow leads you to survive millions of years, which itself is a rather small accomplishment considering massive timescales, but massive from our perspective of an apparently terminal 10,000 year old civilization.
